This is a 3D-printed scale model of an outdoor space-walking machine (fitness walking machine), accurately replicating the most common outdoor fitness equipment found in community parks.

The model faithfully reproduces the full functional structure of the real walking machine, with color-separated design that perfectly matches the classic color scheme of the actual device:

• The black components form the core load-bearing frame, including two main upright posts on the left and right, a top connecting beam, and a bottom fixed base, creating a stable gantry-like support structure that mirrors the rigidity of the real equipment;

• The yellow components are the movable functional parts, comprising two sets of oscillating arms, non-slip textured foot pedals, and impact-resistant decorative caps at the top of the upright posts, fully recreating the core operating mechanism of the walking machine’s dual arms and dual pedals; even small-scale details such as the non-slip texture have been precisely reproduced.

• The model has been divided into separate parts, so multi-color printing is not required.

• The assembly steps are as follows:

  Prepare all printed parts
  First, insert the nut-equipped fittings into the upright posts (identical on both sides)
  Then insert the handrails, bending them upward
  Next, insert the circular fittings and screw on the post nut caps
  Then insert the foot pedals into the pedal connecting rods; if they feel loose, apply a bit of glue.
  Insert the two pedal connecting rods into the screw holes of the post fittings
  Screw on the hex nuts to complete the installation.
